RunnerScriptの内部でurl_forを使う方法
以下をlib/hoge.rbとして保存(config/routes.rbは設定済み)
include ActionController::UrlWriter default_url_options[:host] = "hoge.org" p url_for(:controller => 'sessions', :action => 'new') p new_session_url
実行すると以下のようになる
% ./script/runner lib/hoge.rb "http://hoge.org/session/new" "http://hoge.org/session/new"
ActionController::UrlWriter.default_url_options[:host]を指定しない場合は以下のようなエラーになった。
